Planning laws inhibit prosperity. That's what we're told by almost everyone. Those long and tortuous negotiations over what should be built where are a brake on progress. All the major parties and most of the media believe that we would be better off with less regulation, less discussion and more speed. Try telling that to the people of Spain and Ireland.

Town planning in those countries amounts to shaking a giant dustbin over the land. Houses are littered randomly across landscapes of tremendous beauty, and are so disaggregated that they're almost impossible to provide with public services. The result, of course, is a great advance in human welfare. Oh, wait a moment. No, it's economic collapse followed by mass unemployment. Spain and Ireland removed the brakes on progress and the car rolled over a precipice. Their barely regulated planning systems permitted the creation of property bubbles that trashed the economy along with the land.

Needless to say, we have learned nothing from this. Our lords and masters still whip the buttocks of the Gaderene swine. When the infrastructure bill was discussed in the House of Lords last week, our unelected legislators rained curses upon peace and quiet, beauty and stillness.

Lord Adonis, a Labour peer, complained that "for the first time in 350 years, Britain will no longer have the world's largest port or airport. That accolade will pass, symbolically, to Dubai". The shame of it – to have some upstart petro-city making more noise and pollution than we do. For the government, Baroness Kramer boasted that "we are making the biggest investment in roads since the 1970s". The Conservative peer Lord Jenkin, in discussing the new freedoms for frackers the government proposes, celebrated what he called a "drill, baby, drill bill". All this, we are assured, will enhance the life of the nation.

The only thing likely to induce more traffic growth, they argued, is building more trunk roads, and that would put intolerable pressure on the city streets into which they feed. The facts might have changed, but the policy remains the same. The department continues to make the same failed forecasts, using the same failed model. The desire to build – and to appease the construction industry and motoring lobby – comes first, and the forecasts are made to fit.

So is the planning system. The government's draft national policy statement for major roads weakens the protection of wildlife, ancient woodlands and treasured landscapes. It forbids any consideration of climate change during planning inquiries: motorways will officially produce no more carbon dioxide than cycle paths.

Not a word of this was heard in the chamber last Wednesday. No one questioned the need for the road-building programme of which the government boasted. The peers, an unlikely club of boy racers, stood only to demand that we should go further and faster, on a journey without purpose or destination.

If they have their way, we will become the proud recipients of a new network of roads to nowhere. Like Benidorm's In Tempo towers, the tallest residential buildings in Europe, they will be commissioned in a convulsion of optimism and greed, before becoming monuments to bad debt and human folly. "Round the decay of that colossal wreck, boundless and bare…".

Campaigners and opposition peers fear that the bill could also licence the government to sell off any public land it chooses, while cancelling, without process or debate, public access and use. Clauses 21 and 22 allow it to transfer property from other public bodies to the Homes and Communities Agency and permanently to extinguish easements (rights of use), public rights of way, and the protections afforded to consecrated ground. The HCA can then sell this land to developers, free from public rights.The news site

Schnews reveals that during the great battle over the coalition's attempt to sell off the public forest estate, which resulted in the government's first major U-turn, one of the campaigners received an anonymous call from a civil servant. "The forests are just the start," he warned. "They are absolutely determined to sell every scrap of public land – beaches, parks, the lot."

Is that what this is? I don't know. During the Lords debate, Baroness Kramer insisted that this measure applies only to "surplus land" and "applies only to private rights and not to those that are public". Just one problem: there are no such safeguards in the bill. The word "surplus" does not occur anywhere, and the bill creates specific powers "to extinguish public rights of way". Yes, public – not private. Had Kramer read the bill she moved? Or was she making it up as she went along? In either case, until this is either clarified or struck out, the forests for which we fought so hard and, perhaps, all other state-owned land could be at risk.

But who needs all that, when you have the world's biggest airport to boast of, and the biggest investment in pointless roads since the 1970s and a "drill, baby, drill bill"? What else would anyone who loved this country wish for?

• This article was amended on 27 June 2014 to remove two paragraphs that misunderstood the effect of schedule three of the bill. It incorrectly stated that schedule three would "license the government to sell off any public land it chooses, while cancelling, without process or debate, public access and use". This has been corrected.
